i assume it's an interactive wrapper for gnu grep that trims leading
white space from the matched lines

ripgrep has a --trim flag for this btw:

  % rg -w Inf Src/params.c
  5756:	    fprintf(fout, (dval < 0.0) ? "-Inf" : "Inf");
  5765:	    ret = dupstring((dval < 0.0) ? "-Inf" : "Inf");

  % rg --trim -w Inf Src/params.c
  5756:fprintf(fout, (dval < 0.0) ? "-Inf" : "Inf");
  5765:ret = dupstring((dval < 0.0) ? "-Inf" : "Inf");
